Exact form would be 3/2, -1/2
Answer:
Thickness is 6 m.
Step-by-step explanation:
Given:
Area of the base of rectangular wood, ![A=120\textrm{ }m^{2}](https://tex.z-dn.net/?f=A%3D120%5Ctextrm%7B%20%7Dm%5E%7B2%7D)
Volume of the rectangular wood, ![V = 720\textrm{ }m^{3}](https://tex.z-dn.net/?f=V%20%3D%20720%5Ctextrm%7B%20%7Dm%5E%7B3%7D)
Volume of the rectangular wood is given as,
![V=A\times h](https://tex.z-dn.net/?f=V%3DA%5Ctimes%20h)
Where,
is the thickness of the rectangular wood.
Plug in
for
and
for
. Solve for
.This gives,
![V=A\times h\\ 720 = 120\times h\\ h = \frac{720}{120}=6\textrm{ m}](https://tex.z-dn.net/?f=V%3DA%5Ctimes%20h%5C%5C%20720%20%3D%20120%5Ctimes%20h%5C%5C%20h%20%3D%20%5Cfrac%7B720%7D%7B120%7D%3D6%5Ctextrm%7B%20m%7D)
Therefore, the thickness of the rectangular wood is 6 m.
Answer:
LBC is 75 degrees
Step-by-step explanation:
When you follow the angle measurements from the first and when one line equals 180, figuring out the other angle measurements can determine the answer for LBC.
A prime number is a number that has only two factors: 1 and itself
For example, the number 7 has two factors: 1,7 This makes 7 a prime number
Since the number has to be greater than 50, we can go to the next whole number; 51
51 has four factors, 1,3,17,51 This is not our prime number
52 is even so obviously it's not prime because you can divide by two
53 has only two factors; 1,53 This means that its prime and the answer is 53 :)
If you have any questions feel free to ask
Answer:
a). 18
b). 26%
c). 39
Step-by-step explanation:
Given question is incomplete; here is the complete question attached.
a). In this part we have to calculate the number of the people surveyed who make less than 5 calls.
From the given table,
Number of people surveyed who make less than 5 calls Or 1 - 4 calls = 18
b). Total number of people surveyed = 18 + 11 + 5 + 3 + 2 = 39
Number of people surveyed, make at least 9 calls = 5 + 3 + 2 = 10
Percentage of these people = ![\frac{\text{People who make calls more than 9 calls per day}}{\text{Total number of people surveyed}}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BPeople%20who%20make%20calls%20more%20than%209%20calls%20per%20day%7D%7D%7B%5Ctext%7BTotal%20number%20of%20people%20surveyed%7D%7D%5Ctimes%20100)
= ![\frac{10}{39}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B39%7D%5Ctimes%20100)
= 25.64%
≈ 26%
c). Total number of people surveyed = 18 + 11 + 5 + 3 + 2 = 39
